Be 111 known that I, HERMANN WOLFER- MANN, M. D., a. subjeet 0f the German Emperor, residing at F0rkelma.rkt 9, Strasburg, Germany, h2we invented cernain 118W and useful Improvements in Truss-Pads, (f0r Whieh I have received patentsas follows: in Germany, N0. 85,144, dated .Iune 21, 1895; in Franee, N0. 237,761,da130d September2, 1895; in Austria,No. 46/ 1,963, dated Ocoober 17, 1895, and in Switzerland, N0. 11,879, dated January 6, 1896;) and I d0 hereby declare the following '00 be a full, 0lea.r, and exa0t deseription 0f 11110 invention, such as will enable 0thers skilled in nhe art 00 which it appertains 110 make ancl use the same.

The drawings annexed '00 the present de- S0ripti0n show the new truss-pad.

Figure 1 is a horizontal section 0f the trusspad. Fig. 2 is a cross-section online A B 01": Fig. 1. Fig. 3 is a p1an view wihout the upper pa.cl. Fig.4. is a similar view with the upper pad.

Ab 0he t0p 0f a steel spring h, which su'rrounds the pelvis between the edge 0f the os innominaum (nameless bone) ancl the pubis, is screwed a plate carrying a pad c, having an elongated shape, the slight external curve 0f Whi0h is directed towa.rd the abdomen. The plate earrying a. pad c is connecbed in front, by means 0f a hinged plate h, 00 an- 0ther pla.te b, earrying likewise a pad a.

The pad of the pla1ze b is 0f porous indiarubber havin,q the highest possible degree of resilieney. This pad a is raised sidewise and serves to prevenb any unclue pressure 011 1she pa.r1zs ancl hence the abrasions of the skin which may result therefrom. The curvature 0f the pad c, Which is direct-ed toward the abdomen, requires a eorresponding eurve f0r 13110 neck 0f ti1e spring. The plate b has a tenclency '00 keep back from the plate c under the pressure of a. spring e, inserted bebween them; 101115 the mova.ble stop-piece f permits 0f this plante b heilig fixed 130 0he pla.te c. This arrangement produces the following results: First, the eompression of the inguinal canal throughout its length is ca.rried 0n in such a manner tha1; the fr0nt a.nd rear Walls ond, 'Dh6 peritoneum is pushed backward, so that insteacl of bulging forward it bulges rearl are firmly pressed 0ne agains1s tl1e otlier; sec- 50 wardly; third, the internal opening 0f the in guinal canal is elosed in consequence 0f this compression, While leavin g the external 0pening 0f this 02.1101 entirely free, so aus 130 prevent the entranee of the inoestines ancl of the epiplon inn0 the inguinal canal; fourtzh, tl1e pressure exerted 011 the plate directed towa.rd 0he abclomen ancl carrying tl1e convex indiarubber pad insures,owing t0 the spiral spring, (the tension 0f whieh 02m be regula.ted by means 0f a wedge w so as 130 correspond 130 a pressure 0f from one-half to f0ur kilos,) an ad j ustable pressure 0n 0110 ruptured part that can be varied ab Will, whereby excessive pressure and consant pain, with 0he ac0ompanying evils, are entirely avoided.

Tl1e truss is fixed by means 0f a perforated belt 0r str-ap starting from the posterior end 0f 0h0 steel spring. The hernial bilateral bandage is fixed by means 0f a perforated bel0 in front.

The freut end 0f the pad,which is held away fr0m the abdomen and carries the stud f0r hooking thereto the fixing-belt, is brought close t0 the abdomen by the tension 0f the belb, which has f0r its objeet 00 oause the laberal end of the pad 00 sink more deeply into the abdomen.

Having thus particularly described my invention, I deelare that what I claim is In a truss-pad for inguinal and serotal hernia, the combination with a plate provided With a pacl c curved outwardly and secured 00 a supporting-spring, 0f a seeond pla.e O arranged below the firsb plante a.nd oscillating upon a hinge, said second plate beingconvex like the first pla0e ancl carrying a. pad a, 0f a spiral-spring e separating said plates, and 0f a. wedge w for adj usting 0he separating force 10etween said plates substantially as described.

In testimony whereof I a.ffix my signature in presen0e 0f two witnesses.

HERMANN WOLFERMANN.
